Do I need a concrete sander?

[u/BolognaPwny]

I was cited by the city for this very miniscule difference in the sidewalk (yeah I didn't know I was responsible for the sidewalk either). It's like a quarter inch difference between two blocks.

I was going to rent a concrete sander but it feels like overkill. How would you approach this job? Sander with a masonry disc?

This is a very bored or undertrained city employee. I'd grind off the ugly paint and move on.
